2.14 - Installing the Power Supply
There are three power connectors on your Thunder K8WE.
The Thunder K8WE requires an EPS12V/SSI EEB 3.51 (24 pin + 8 pin) power
supply to boot. TYAN recommends using a split plane power supply because of
the amount of power the S2895 requires.
You also have an option of using an SSI v3.51 workstation power supply. This
is recommended when running both PCI Express slots.
WARNING
Please be aware that ATX 2.x and ATXGES power supplies are not compatible
with the board and can damage the motherboard and/or CPU(s).
This chart represents SSI EEB 3.51 split plane power supply.

NEVER plug the 8-pin power connector into the 6-pin
connector. Doing so will damage the motherboard and/or
other components.
